General Controls

The following are typical controls that you will use in the Trim Edit window.

  • Current sequence timecode: Shows the timecode number of the currently viewed edit point in the sequence. You can type a plus sign (+) or a minus sign (-) and a timecode duration to adjust the edit forward or backward using the current mode (ripple or roll).
  • Green bar: Indicates what kind of trimming operation you’re about to perform:
    • On the left side (over the outgoing clip): A ripple edit to the outgoing clip’s Out point
    • On the right side (over the incoming clip): A ripple edit to the incoming clip’s In point
    • Over both: A roll edit to the edit point between both clips

    You can switch between these operations by pressing U or by clicking the relevant part of the Trim Edit window (as described in Trimming an Edit in the Trim Edit Window).

  • Scrubber bar: The scrubber bar runs along the entire width of each of the two viewer areas in the Trim Edit window, below the video image. To scrub, or move, through a clip or sequence, drag the playhead across the scrubber bar. You can also click anywhere in the scrubber bar to instantly move the playhead to that location.
  • Jog control: The jog control allows you to move the playhead as if you were actually moving it with your hand, with a one-to-one correspondence between the motion of your mouse and the playhead’s motion. For more information, see Viewer Basics. You can also refer to Canvas Basics.
  • Shuttle control: This control lets you quickly play through clips and sequences at different speeds, in fast and slow motion. Drag the slider to the right to fast-forward and to the left to rewind. Playback speed varies depending on the distance of the slider from the center of the control. For more information, see Viewer Basics. You can also refer to Canvas Basics.
Transport Controls

The Go to Previous Edit and Go to Next Edit buttons allow you to change which edit point in your sequence is shown in the Trim Edit window. Other controls allow you to play back only the edit you’re trimming to see how it works.

  • Go to Previous Edit: Click to move the previous edit point in your sequence into the active area of the Trim Edit window.
  • Play In to Out: Click to play from the beginning of the first clip to the end of the second clip.
  • Play Around Edit Loop: Click to play from a point before the current playhead position to a point following. The time intervals before and after the playhead position are determined by the preview pre-roll and post-roll settings in the Editing tab of the User Preferences window. For more information, see Choosing Settings and Preferences.
  • Stop: Click to stop playback and position the playhead on the edit point.
  • Go to Next Edit: Click to move the next edit point in your sequence into the active area of the Trim Edit window.
Playback Controls for Individual Clips

These controls allow you to move the playhead on either side of the edit point without modifying the edit point itself. The outgoing and incoming clips have separate playback controls, which can also be controlled by the J, K, and L keys. The playback controls are for viewing only; they don’t change the position of an edit point.

Important: The Space bar plays around the selected edit point in the Timeline; it does not control playback in either side of the Trim Edit window. For more information, see Playing Incoming and Outgoing Clips in the Trim Edit Window.

  • Previous Frame: Use this control to jog the clip backward, one frame at a time.
  • Play: Use this control to play the clip at normal speed.
  • Next Frame: Use this control to jog the clip forward, one frame at a time.
Trim Buttons

These controls let you trim clips as well as turn trimming on and off.

  • Trim Forward and Trim Backward: Click these buttons to add or subtract frames from the duration between the In and Out points.

    You can set the –5 and +5 buttons to trim a different number of frames by changing the Multi-Frame Trim Size setting in the Editing tab of the User Preferences window. The number of frames to trim can be set from 1 to 99. For more information, see Choosing Settings and Preferences.

  • Dynamic Trimming: Select this checkbox to turn dynamic trimming on and off, without having to go to the User Preferences window. For more information, see Dynamic Trimming.
Outgoing Clip Area

Use these controls when trimming the outgoing clip.
